IMPROVED REVERSIBLE KNOB-LATCH. i

The Schedule referred to in these Letters Patent and making part of the same.

To all 'whom it may concern: j

Be it known that I, F. P. PFLEGHAR, of New Haven, in the county of New Haven, and State of Gonnecticut, have invented a new Improvement in Knob- Latche'syaud I do hereby declare the following, when taken -in connection withthe accompanying drawings, and the letters of reference marked thereon, to be a full, clear, and exact description of 'the same, and which said drawings constitute part of this specifica-VA Figure l, a view'oi the lock, the plate removed to show the interior; and in Figures 2, 3, and 4, sectional views, to illustrate the operation.

This invention relates to an improvement in knoblatches, the object being to make' the bolt reversible for a right or left-hand door;,and The invention consists in the arrangement of a bolt in a socket, (the socket being moved by the follower within the case,) so lthat the bolt may be turned to G, the latch-bolt, is vformed with a round tail-piece, L, which fits into the socket F, and in the said tailpiece is a spring-catch, a, arrangedso that when the latch-bolt isset into the socket, the catch a will spring into a recess through the socket, as seen in figs. 1 and f' The square part of the latch-bolt, restingin the face-plate, guides it into position; and when it is de.

sired to reverse the latch-bolt, as from the position in iig. 2 to that in fig. 4, press the spring-catch in, and withdraw the holt partially from the socket, as denoted in g. 3.` The withdrawal is for the purpose of clearing the square part of the bolt from the faccplat'e. In this position the bolt is easily turned to the vposition in red, iig. 4, then pressed into the socket. The catch i'es into a corresponding recess or opening in the socket, as seen in fig. 4.

Through the case, upon both sides, an opening is made, as at al, through which to press upon the springcatch, when it is desired to reverse the latch.

l do not, broadly, claim the arrangement of the latch-bolt, so as to be reversed in thesocket.

Having fully described my inventon,

\Vhat I c lairn' as new and useful, and desire to secure by Letters Patent, is-

yThe arrangement of the latch-bolt G, in the socket F, so as to be reversed inthe manner described, andv held in position by the spring-catch a, in the tail-piece of the bolt, as and for the-purpose set forth.

F. P. PFLEGHAR.
